DESCRIPTION
The MSP Zero-Leak inlet shut-off valve is designed for use in oil
only header lines, for the lubrication of extended systems and/or
systems with varied lube frequencies. Such applications include
automotive transfer lines, conveyor lines, flexible machining
centers and also complete plant lubrication.
The MSP Zero-Leak inlet shut-off valve can be mounted as the
inlet section to any primary (master) divider valve assembly. By
using a remote manifold kit, it can be teed off of the header line
to a remote primary (master) divider valve assembly.
The MSP Zero-Leak shut-off valve is supplied normally closed to
flow. When the coil is energized, the zero-leak valve is opened,
allowing oil to flow through. Once the proper amount of oil has
been dispensed, the valve is de-energized, shutting off oil flow.
The Zero-Leak valve is designed for header-line pressures up to
1500 psi.
FEATURES/BENEFITS
Designed for use with an oil header line system, which is •
an economical method of providing lubricant to extensive
systems. Reduces plumbing and installation cost.
When used in a header line system, lubrication zones are •
easily extended or deleted as changes are made to the lube
circuit. This reduces engineering design costs.
Enables individual zone lubrication. Prevents over •
lubrication thus saving on lubrication costs.
Facilitates individual zone operation and monitoring. •
Identifies a fault in a specific zone for ease of
troubleshooting. Helps lessen machine downtime, which
means more production time.
Solenoid can be rotated through1800 to accommodate •
any electrical hook up --orientation. Allows for faster
installation to reduce costs.
Available with three pin mini-connection as standard•
Available with NPSF pipe, BSPP or SAE, o-ring sealed ports. •
Inlet restrictor/filter available for use in continuous •
pressurized header line systems. This will slow down lube
inrush and enable accurate control of the lube systems.
Order Part Number 563074 (463-410-204) for NPT pipe
inlet.
Coil is molded and sealed, making it impervious to coolant. •
Allows mounting of valve in harsh environments.
OPERATION
The MSP Zero-Leak inlet shut-off valve is used in conjunction
with an oil header line lube system with each shut-off valve
representing a zone of lubrication (See Fig.1). The header line
can either be continuously (use restrictor) or intermittently
pressurized upon demand. When the particular machine zone
requires lubrication, based upon a pre-determined interval, an
electrical signal from a Trabon Flexi-Monitor
®
or machine PLC
will sequentially energize the solenoids attached to the shut-
off valves (A1), (A2), and (A3). This will open the valve and
allow lubricant from the header line to cycle the divider valve,
thus providing lubricant to the points within the zone. Once the
zone has received the proper amount of lubrication, determined
through monitoring the cycle switch (B) or proximity switch (B)
for appropriate number of cycles, the controller will de-energize
the solenoid and the valve will shut-off lubricant flow.
